"Hundreds of thousands of children still at risk from dangerous levels of air pollution as poisonous smog fills cities, study says"
"Emissions from coal plants in China were responsible for a quarter of a million premature deaths in 2011 and are damaging the health of hundreds of thousands of Chinese children, according to a new study.
The study by a US air pollution expert, commissioned by Greenpeace, comes as many areas in northern and eastern China have been experiencing hazardous levels of air pollution in recent weeks.
In some eastern cities including Shanghai, levels were off the index that tracks dangerous pollution, with schools closing and flights being cancelled or diverted. Sales of air purifiers and face masks have soared with many retailers selling out of stock as residents try to protect themselves from the poisonous smog. In Jiangsu and Zhejiang provinces visibility was reduced to less than 50 metres earlier this week and in the city of Nanjing a red alert for pollution was maintained for five consecutive days."
